The Role Of Brct-Containing Proteins Brca1 And Paxip1 In Cancer, Ankita Jhuraney

USF Tampa Graduate Theses and Dissertations

Modular domains of proteins are important in cellular signaling processes. Eukaryotic cells are constantly undergoing DNA damage due to exogenous and endogenous sources of damage. The DNA damage response (DDR) involves a complex network of signaling events mediated by modular domains such as the BRCT (BRCA1 C-terminal) domains. Therefore, proteins containing BRCT domains are important for DNA damage detection and signaling. In this dissertation, we focus on two BRCT-containing proteins BRCA1 and PAXIP1. BRCA1 is a gene that is known to be associated with increased risk of hereditary breast and ovarian cancer. Germline variants of BRCA1 are assessed to determine …
